Whichever style of wheel you choose, you have to make sure they will fit your 4x4 properly. The right way to measure backspacing is to lay a straight edge across the rear edge of the wheel and measure to the mounting flange. Start with the wheels and tires you have now, and determine what backspacing you'll need in order to fit the wider tires that you're likely installing with your new wheels. See the main article for an example.
